Summary
Training pigs, providing more ropes, and extending sampling time improve participation in pen-based oral fluid collection for swine disease surveillance. These methods maximize pig contribution to samples.
Area of Science:
- Veterinary Medicine
- Animal Science
- Swine Health
Background:
- Pen-based oral fluid collection is vital for swine disease surveillance.
- Limited data exists on optimizing the sampling process for maximum pig participation.
Purpose of the Study:
- To optimize pen-based oral fluid sampling in pigs.
- To determine factors influencing pig participation and rope contact during sampling.
Main Methods:
- Quantified effects of training, number of ropes, and sampling time on pig participation.
- Video recorded individual pig interactions with ropes, defining 'contact' as mouth-rope interaction.
- Analyzed data using statistical models (R version 4.4.1).
Main Results:
- Training pigs, increasing the number of ropes, and extending sampling time significantly boosted pig participation.
- All tested factors increased pig engagement across different pen sizes.
Conclusions:
- Recommend training pigs before sampling and increasing sampling time for routine oral fluid collection.
- These strategies maximize pig contribution to oral fluid samples.
- Future research should assess the impact of these factors on disease detection probability.
